Diagnostic Test
WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
- DTC IS ACTIVE
- Turn the ignition on.
- With the scan tool, Clear DTCs in the Powertrain Control Module (PCM).
- With the scan tool, actuate the SRV Solenoid Control State.
- With the scan tool, select View DTCs.
Is the status Active for this DTC?
Yes
- Go to step 2
No
- Perform the CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
- (F343) ASD RELAY OUTPUT CIRCUIT OPEN OR HIGH RESISTANCE

- Turn the ignition off.
- Disconnect the Short Runner Valve Assembly harness connector.
- Turn the ignition on.
- With the scan tool, actuate the Auto Shutdown (ASD) Relay Control State.
- Using a 12 volt test light connected to ground, check the (F343) ASD Relay Output circuit in the Short Runner Valve Assembly harness connector.NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
Is the test light illuminated and bright?
Yes
- Go to step 3
No
- Repair the (F343) ASD Relay Output circuit for an open circuit or high resistance.
- Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
- (K236) SRV CONTROL CIRCUIT SHORTED TO GROUND
- Turn the ignition off.
- Measure the resistance between ground and the (K236) SRV Control circuit in the Short Runner Valve Assembly harness connector.
Is the resistance above 100 ohms?
Yes
- Go to step 4
No
- Repair the (K236) SRV Control circuit for a short to ground.
- Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
- (K236) SRV CONTROL CIRCUIT OPEN OR HIGH RESISTANCE
CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals, resulting in poor terminal to pin connection. Install Miller Special Tool #8815 to perform diagnosis.
- Measure the resistance of the (K236) SRV Control circuit between the Short Runner Valve Assembly harness connector and the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes
- Go to step 5
No
- Repair the (K236) SRV Control circuit for an open circuit or high resistance.
- Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
- Measure the resistance of the (K236) SRV Control circuit between the Short Runner Valve Assembly harness connector and the appropriate terminal of special tool #8815.
- SHORT RUNNER VALVE ASSEMBLY
- Connect the Powertrain Control Module (PCM) connector.
- Connect the Short Runner Valve Assembly connector.
- Using a 12 volt test light connected to 12 volts, check the (K236) SRV Control circuit in the Short Runner Valve Assembly harness connector.
- Turn the ignition on.
- With the scan tool, actuate the SRV Solenoid Control State to toggle.NOTE: If the DTC is active, the actuation test may not be allowed by the PCM. If may be necessary to clear the DTCs before starting the actuation.NOTE: The test light should illuminate on and off with the actuation.
Does the test light illuminate on and off with the actuation?
Yes
- Replace the Short Runner Valve Assembly in accordance with the Service Information.
- Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
No
- Go to step 6
- POWERTRAIN CONTROL MODULE (PCM)
- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Short Runner Valve Assembly and the Powertrain Control Module (PCM).
- Look for any chafed, pierced, pinched, or partially broken wires.
- Look for broken, bent, pushed out or corroded terminals.
- Refer to any Technical Service Bulletins that may apply.
Were any problems found?
Yes
- Repair as necessary.
- Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
No
- Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information.
- Perform the PCM VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
